3. Notified under Article 2.9.2 [X], 2.10.1 [   ], 5.6.2 [   ], 5.7.1 [   ], other :  
4. Products covered (HS or CCCN  where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  Springs - 
Quality Requirements - Cylindrical Helical Compression Springs; Springs and leaves for 
springs, of iron or steel (HS 7320)  
5. Title, number of pages and language(s) of the notified document:  Communiqué 
On TS 1441 -1 "Springs - Quality Requirements - Cylindrical Helical Compression Springs 
- Part 1: Made From Round Wire And Rods, Hot Formed" and TS 1441 -2 "Cylindrical Coil 
Compression S prings Made From Round Rods - Part 2 : Quality Requirements For Mass 
Production" (3 page(s), in English)  
6. Description of content:  This standard; covers the characteristics of hot -formed 
cylindrical -helical compression springs from circular bar in descri ption, classification and 
specifications, sampling, inspection and testing, and based on market supply. The 
permissible deviations specified in this standard apply to helical compression springs that 
meet the following requirements:  
- Party size up to 5000  pieces  
- Rod or wire diameter,   d 8 mm to 60 mm  G/TBT/N/TUR/151  
 
- 2 - 
 
  - External coil diameter,  De ≤  460 mm  
- Unloaded spring length,  L0 ≤ 800 mm  
- Number of active turns ,  n ≥ 3  
- Turns in rate, w 3 to 12  
In cases where the party size is 5000 pieces or more, TS 1441 -2 is app lied. This standard 
covers the description and testing of   cylindrical helical compression springs made of 
round bar. Springs covered by this standard are mainly used in vehicle 
suspensions.Vehicle suspension springs are generally manufactured in large sca le and in 
automatic production lines. Therefore, manufacturing tolerances are narrower than 
TS 1441-1. The permissible deviations specified in this standard, cylindrical helical 
compression, which meet the following requirements:  
- Mass production At least  5000 pieces  
- Rod length, l, up to 4300 mm  
- Rod diameter, d 9 mm to 18 mm  
- Unloaded spring length L0 (free length) up to 600 mm  
- External coil diameter, up to 180 mm  
- Number of active turns n from 5 to 12  
- Turn index, w 6 to 12  
- Total spring deflection sc 180 mm and more  
- In cases where the group size is 5000 pieces or more, TS 1441 -2 is applied.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  The purpose of this Communiqué is to identify is sues related to the 
implementation of revision of TS 1441 -1 "Springs - Quality Requirements - Cylindrical 
Helical Compression Springs - Part 1: Made From Round Wire and Rods, Hot Formed" and 
TS 1441 -2 "Cylindrical Coil Compression Springs Made From Round R ods - Part 2 : Quality 
Requirements For Mass Production" standards.; Other  
8. Relevant documents:   
• TS 1441 "Helical Compression Springs Made of Round Rod; Warm Coiled" 
standard.  
9. Proposed date of adoption:  The regulation will be adopted upon its publication.  
Proposed date of entry into force:  The regulation will enter into force 6 months after 
its publication.  
10. Final date for comments:  60 days from notification  
11. Texts available from:  National enquiry point [X] or address, telephone and fax 
numbers and email and website addresses, if available , of other body:
